- Icthyoses (genetic e.g icthyosis vulgaris as well as acquired);

- Certain malignancies like lymphomas can also present with severe dryness of skin.
- Ageing is also a cause of Xerosis; people in old age frequently complain of dry skin as compared to when they were young.

Management of Xerosis is symptomatic i.e regular use of moisturisers and correction of underlying disease e.g hypothyroidism
